Texas Instruments manufactures many types of scientific and graphing calculators, each designed to make a wide range of calculations, from simple addition and subtraction to creating graphs from complex formulas. One feature on all Texas Instrument calculators is the square root function, which automatically solves the square root of the number inputted to the calculator. The square root of a number is the number that is multiplied by itself to form the number. For example, "10 x 10 = 100," so the square root of 100 is 10.
